Z8530_NULL_RX(9) Public Functions Provided Z8530_NULL_RX(9)NAME
z8530_null_rx - Discard a packet
void z8530_null_rx(struct z8530_channel * c, struct sk_buff * skb);
The channel the packet arrived on
We point the receive handler at this function when idle. Instead of processing the frames we get to throw them away.

IEEE80211_GET_BUFFER(9) Advanced driver interface IEEE80211_GET_BUFFER(9)NAME
ieee80211_get_buffered_bc - accessing buffered broadcast and multicast frames
struct sk_buff * ieee80211_get_buffered_bc(struct ieee80211_hw * hw, struct ieee80211_vif * vif);
pointer as obtained from ieee80211_alloc_hw.
struct ieee80211_vif pointer from the add_interface callback.
Function for accessing buffered broadcast and multicast frames. If hardware/firmware does not implement buffering of broadcast/multicast
frames when power saving is used, 802.11 code buffers them in the host memory. The low-level driver uses this function to fetch next
buffered frame. In most cases, this is used when generating beacon frame.
A pointer to the next buffered skb or NULL if no more buffered frames are available.
buffered frames are returned only after DTIM beacon frame was generated with ieee80211_beacon_get and the low-level driver must thus call
ieee80211_beacon_get first. ieee80211_get_buffered_bc returns NULL if the previous generated beacon was not DTIM, so the low-level driver
does not need to check for DTIM beacons separately and should be able to use common code for all beacons.
